Sennheiser RS120-II (DISCONTINUED)If you're looking for a sub £100 wireless headphone then you can't go wrong with the RS120-II. The transmitter can charge the headphones and uses RF (radio frequency) to transmit audio - this gives you a very long range but can be susceptible to interference. The headphones are open back so they will leak sound - but will provide a natural sound with good width.
TV Ears 2.3 (DISCONTINUED)For the hard of hearing, the TV Ears 2.3 is very hard to fault at the very low price of £59.95. They use infra red to transmit audio so you get a clear sound, they are susceptible to interference though. The sound quality is what you'd expect for the price but as they are designed for the hard of hearing their main focus is on the upper frequencies - so for this purpose they work very well.
